variety ofV positions relative to the work, andV to so support the tool head that it maybe moved in any direction relat ve to the body of wood or other subst-ance on which shaping or forming operations are to be performed.

It is an object of the invention to provide a support, such as a table, for the work, and a superstructure above 'the table with correlated structural parts for holding the tool head in suspension above the table and enabling the tool head to be moved in any desired direction relative to the table, thereby malring it possible to apply cutting, forming and finishing tools to a body supported on the table, advancing the tools in the directions required to reduce the body to the desired form.

It is an o iect ot the invention to provide in a device having the characteristics set forth above means for mechanically feeding the tool head in its various directions, such means being detachable and the tool head then being lett tree to be manually moved to malte the desired cuts. Y

lt is an object of the invention to provide a woodworking machine especially suitable for making duplicate parts or duplicate operations on different par-ts through the setting oi proper stops and the use of master patterns across which a tracer or follower held in the tool head may be carried, and it is al further object to provide a woodworking machine which may be operated with great safety to the operator tor the reason that in the use of such machine the work is held stationary'in position and the C esiredtools are then moved across the work, instead of the present practice of moving the work across the rapidly rotating tools. Y

In the foregoing l have set forth briefly 'certain important objects or myinvention, but other objects and advantages are to be found throughout the following part of' the speciiication, which reiors to the accompanying drawings which are for illustrative purposes only, and in which;*

- thetraveller'22, these plates being of such` `Width as-to extend inwardly beyondthe in- Fig. 12 is an enlarged section on the plane represented by the line 12-12 of Fig. 2, shovving a simple form of clamping mechanism Which may be used in the practise of the invention for locking the longitudinal or cross carriages inany selected position relative to the table. VV 7 Referring lirst to Figs.v 1, 2, 4 and 7, the herein described simple embodiment ofcmy invention includes altable 15 Which is suitably supported on legs 1'6, these legs :being of such length that the table 'Willpbe positioned at approximately the height of an ordinary Woodworking bench. Upwardly extending at the ends of the table 15 are posts 1-8 supporting longitudinal track members 19 which in simp-le form may consists of structural fa-ngles 'having legs2() horizontally -and outwardlyprojected, as shown in Fig. 7, so Xthat the Wheels 21 yof the traveller 22 may rollupon the longitudinal track portions thus provided by the horizontally outstand-V ing legs l20. This traveller22 is in--the form fof a rectangular rame, includin`g side bars 23 made Afrom structural channels Aas best shown in the cross section Fig. 4, and endV plates 24. The traveller 22 has its length direction of extension of the tra'ckmembers 19 on Which the travellerv 22=is movable. The tracks 25 may be, conveniently formed by securing plates 27 to the bottom legs 28 oi the side-channels`23 forming the side members of ner ,faces of the members 23 inthe fmanner shown inv Fig. 4, thereby forming inwardly yeo projectingrparallel Vvledges lor tracks -25 on Which the Wheels or Lrollers 30 of the cross- Y carriage 3l may run,-this cross-carriage being'so termed for the reason of its cross movement relative tothe longitudinal axis of the Woodworking machine. The cross-carriage 31`may 'beconveniently made from a rectangular plate' 32having 'the vrollers 30, which are four ininumbensecured thereto on shaft bolts33. f j Y f -As shown best in Figs; 1, 2,"a'nd 7 structural angles 35 may be Ysecured across the tops 'of thechann'el members 23 of 1the' `traveller 22 knear the ends thereof,I and with legs 36 up-y wardly proj e'ctingpairallelto the outer edges ofthe track 'members 19 asshown in Fig. 27.,

soas to Aprovide Vmeans "whereby" the -shafts 37 on which the rolflers'or Wheels-21 operate,

lmay be sec'ured Eto the traveller Y From -thefcre'going it will be seen that lthe lelements of my kstructure includefa'horzontal Lassie?? table 15 having a length possibly three times the Width thereof, a horizontal track member' supported above the table in position parallel to the top of said table, a longitudinally movable traveller which may travel on the longitudinal track members from onevend of the table to the vother in -a plane parallel to the top off the table. VThe traveller 22 which is longitudinally movable, carries in it a crosscarriage Which is adapted to move in the vcrossltracks of the traveller, across the top of the table, ina line at right angles to the length of the table. It Will'be seen that by moving the traveller`22 and the cross-carriage 31 simultaneously, any direction or angle of movement of "the cross-carriage maybe ob- -tained,fand it-'ma'y b'estoppedand clampedin position above any part ofthe-table 15.

1 'In Figs.2 and 4 'I show ia vertical-column 40 projecting down from the 'crossicarriage ,31, this column 40 havinfgsthe purpose of'sup-l porting in operative position a Workingfhe'ad or tool khead 41, there beingfa Acylindrical Wall 42 in'su'bstantially the center Lvof the Itoolhead 41 having a `bore '4B-oa size yto `receivefthe 'lowerendportion of thecolucmn40. Thebottom webV V44 of the tool `head 41 'is preferably fla'tand horizontalfandsupports at its outer edges a 'front Wall 45, rear Wall-46,and leftV and right side ivalls'47 and-48. 'On'ltherlower rear portion of the lcolumn 4() Aarack 49 is secured, which is vertically Valigned and wprojects into fa vertical lchannel 250 in l'the cylindrical Wall 42 so aste fbe engagedbya pinion 52 mounted on a shaft 53 secured in the tool head 41 in position parallel to the .rear Wall 46', in :the mannerxshovvn'in and 74.

'resting 'on-the upperfsur- 'face-of the cross-carriage :31;and providin'ga -iao suspension engagement ffor the Vcolumn 40, which column, as shown, projects through central opening 60 inthe carriage-31. The f Vcolumn 40 Ymaybe rotated on'. its vertical axis through an'angleo'SGOdegreesjthereby inak- `ing it possible -tosvving` the: `tool khead' 411on Va vertical axis and Vrelative ltoithetable 15 v above Which theftoolhead is held inrsuspension. Y FromV the kprecedingparagraph itwilll be soindle 71 su i aorted in a sleeve bearin seen that it is possible to set the front wall ot the tool head 41, which front wall 45 is equipped with a handle 61, parallel to the frontedge of the table as shown in Figs. 1 and 2, or to place the front Wall at an angle of 90 degrees, or other angle, relative to the front edge of the table 15. A ring nut 62 threaded on the upper portion of the column 40 in a position just below the lower face of the cross-carriage 31, may be engaged by a suitable lever 63 and rotated tightly into position against the under-surface of the cross-carriage 31 so as to clamp the column 40 tightly in any position to which it may be rotated for the purpose oi positioning the tool head 41 relative to the table 15 of the woodworking machine.

A motor support 65, hinged at 66 to the rear wall 46 of the tool head 41, supports a motor 67 having a step-cone pulley 68 mounted on the rightwardly projecting end of its shalt, so that such step-cone pulley will be in alignment with a co-operating pulley 69 mounted on the rightwardly projecting end 70 of a tool head spindle 71, which .spindle 71 is mounted at the front end of the tool head 41 in position parallel to the front wall 45 and in aplane below the vertical center of the tool head, thus bringing the spindle into a position in the lower right hand corner of the leftward wall 47 of the tool head 41, as shown in Fig. 4.

Fig. 5 shows the spindle 71 and that portion of the tool head 41 in which the spindle 71 is supported, these parts being in section on the plane indicated by the line 5-5 of Fig. 4. As shown in Fig. 5, the spindle 71 has an axial bore 72, the leftward or forward end of which is outwardly tapered or expanded to form a standard taper tool socket 78 into which the tapered shanks 74 of the various arbors employed in the operation of the machine maybe inserted and securely held. The leftward or forward end oi the spindle 71 projects through the leftward wall 47 to what we shall hereinafter term the working tace 75 of the tool head 41, which working face 75 is the outer vertical face of the leftward wall 47 of the tool head 41.

ln this disclosure of the invention, we are not particularly concerned with the minute `illustration of well known mechanical eX- pedients, therefore the mechanisms employed in the practise of my invention are shown in their simplest forni, it being understood that the most suitable mechanical equivalents may be substituted therefor, such as the substitution of roller or ball bearings in the place of sleeve or friction bearings where I have shown such sleeve bearings throughout the drawings of this application. 1n keeping with this simplilied form of illustration, 1 show the left-ward or forward end of the illstalled in a hub or boss 77 cast integrally with the Wall 47, and I show the rightward end of the spindle 71 supported in a sleeve bearing 78 and having a thrust bearing flange 79 formed thereon adapted to operate between a thrust ring 8O and a thrust adjustment nut 81, in this manner providing both radial and thrust bearings for the spindle 71.

As shown in Figs. 8, 4, and 5, an annular rib 83 projects outwardly from the working face 75, around and concentric with the forward end ot' the spindle 71, this concentric rib 83 having the purpose of centralizing on the working face 75 a swivel or angle head 84, which is shown in vertical position in Figs. 2 and 5. As shown in Figs. 5 and 6, the angle head 84 has an inwardly disposed machined face 85 which engages' the working face 75 oi the tool head 41. Onthe longitudinal axis'of this angle head 84 a spindle 86 is supported inv bearings 87 and 88, the bore 89 of said spindle being enlarged at its lower end to provide a taper socket 90, preferably of size identical to the taper socket 73 of the spindle 71, so that the shanks of tool arbors and attachments may lbe interchangeably employed between the sockets of the spindle 71 and the spindle 86.

A cavity 92 is formed in the center of the angle head 84, this cavity being in open communication with the inner machined face 85, being substantially concentric with the groove 93 formed in the machined face 85 and being of a size to t over the gear 106. The groove 93 in the face 85 of the angle head 84 lits closely over the rib 83 and by this co-engagenient serving t'o establish the position of the angle head 84 on the working face 75, but permitting rotation thereof. For the purpose of securing the angle head 84 in place Iprovide a stud 94 which projects outwardly through a curved slot 95, which slot is termed concentric with the axis of the spindle 71 and the annular rib 88, as plainly illustrated in F ig. 4. The outer end 96 of the stud 94 e);- tends into a hole 97 provided therefor in the body of the angle head 84 and is equipped with a lateral circular hole 98 near its projecting end adapted to be engaged byranfeccentric cylindrical portion, or cam, 99 provided on the inner end of a locking pin 100 which enters the body ont the angle head 84 from the side, as shown in Fig. 6, there being a head 101 or other suitable engagement means on the outer end of the locking pin 100 for engagement of a wrench. By the sim? ple manipulation of the'locking pin 100, the angle head may be quickly clamped in any position on the working face 75 between vertical and horizontal, the setting or" the angle vhead being accomplished by rotating the angle head on its center which is deiined by the cor-engagement ot the annular rib 83 with the groove 93, and then rotating the cam 99 into clamping position. A On the central portion of the spindle 86 a miter gear 105 `isse- Vicured, .this-gearwbeing in proper position to be driven by a vdrivinggear i166 secured on the "arbor 74 whichis fheld in the socket 73 ofthe -spindle 71, there Aibeing pro-vided ineans'for r .locking the :ta-per shank or arbor firm-ly yin o. the taper socket 73,'havingthe form of along l y or article of work 115 which is being formed V -.therefore, byk manipulation of the-handle130 =.in ithe woodworking machine. The motor 6? V'shown in Fig. 3, is adaptedto drive the ftool 'head-spindle 71 of--the tool head 41 by means cfa belt which runs over the step-conepul- `leys 68 and 69. The rotationoi the spindle .-.71 is transmitted through themiter gears 106 and 105 to the verticalV spindle Aoi" the angle head 84, thereby imparting rotation to what- Yever tool, 4such as the 'routerl 114, may be sehead 84. 4` v e ,In Fig. 2of the drawings,l showthe spfndie of `the 'anglefhead 84 vequipped with an arbor 120l having-a dadocutter 121 mounted thereon, the cutting edge of this dado cutter 121 being-shown infengagementwith the edge of the work 115 lheld by :means of clamps 122 and-wood blocks or parallel spacing strips123 in-"position `parallel-to the top of the table o 15. Toadjustffthe vertical position-or height ofthe cutter 121 relative to the edge of the Y work 115, the, elevator handle v55 is rotated .andthe .pinion '52 of Figs; 3 and 4 :is caused -tingrthe -tool head 41 to the desired proper lwerking 'height with vrespect to the-.edge of .the work.1-15. On vashaft125,Fig. 1, extending through the structure of the traveller 22, afsprocket'126 is mounted in proper position v:to engagea rack or chain 127 extending-longi- =.tudi'nally.through the length of the superstructure of the woodworking machine and between .the end plates 128 and 129,` which tie across the ,ends oi:` the longitudinal track By-useofiarfhandle 130 on the outward end of the shaft 125, lthesprocket 126.1nay be ro- Atated,.-znfid through engagement with the V'chain .127 it will-cause the rtraveller 22 to `the direction in which the handle is rotated;

it is .possible lto move .the traveller'22, .the tool V.headl41,.and the .tool 121 into cuttingengageinentfwfi'th the work. p Whenthe proper depth lcured in the/taper socket S05-of the angle to rollvertically on the lrack 49, thereby setmove -in llongitudinal.direction depending on of `cut is thus. established, the handle 1132 may be employed to rotate'a screw 133 extending through the structure .of the traveller 22 and by engagement of thescrew 133 with a vnut 134 attached to the cross-carriage 31, to feed 'the cross-carriage acrossl the table 15 land along the edge of ithe work which extends transverse -relative to the length ofthe table 15, cuttingin theedge-of the work 115 a dado groove or slot 136 such as shown in Fig. 5, or a groove o'fany other form by theuse of a properly shaped tool. 1

AAs shown 'in Fig. 1.1, the Vsprocket 126.y may have rollers 137 cooperative therewith 'for the purpose of holding-the chain 127 in :proper engagement with the teeth of thesprocket. These rollers 137 may-be conveniently held on a vplate 138 securedfat139 tothe side channel 23 ofj the traveller 22. The 'engagementof the sprocket 126 with the-chain ,1127 providesfno 'resistance to movementofthe traveller 22 along the longitudinal track members 19, therefore :it is possible to push the traveller 22`from-one end ofi the table to the other, which would be the .operation `'tollowed lin ripping lumber by useof a saw 140 mounted l in the horizontal spindle 71 of the tool head 41 inthe manner shown in Fig. 7 ,this saw A140 being mounted on an :arbor 142 and such arbor being equipped with the proper taper shank to iit intofthe taper socket 73 of the spindle 71. For longitudinal or rip sawing the column 40 is rotated vto bring the Workbe .made by moving the cross-carriage' 31 along the tracks 25 providedlby the traveller 22, ythis being done by rotation of rthe .feed screw 133 'and the veo-operative engagement therewith of the nut 134 which is lattac'hedto the `cross-carriage 31. When the saw 140 is set in proper alignment, th e motor 67 may be started by proper `manipulationjof Va motor control lswitch 145 convenientlyomounted at the front of the tool head 41 and'while the saw 140 is in rotationtthe tool head may then be lowered, or may have been :previously -lowered, by use ofthe elevatorhandle 55, after which the traveller .may be caused to advance longitudinally byvhand'pressure through engagement of the handle 61, or by means of the longitudinal .feed which is operated through e `manipulation of the handle 130.V The engagementrof-'the screw 133, `Figi. l1, With the nut 134 provides a lock for preventing move.-

rnent ofthe crosscarriage 31, except by operation of thel cross feedhandle 132.

In Fig.V 8 I show a plan view of the table 15 onwhicha.blade148ota protractor .gauge 149 is secured by means of bolts 150, or otherwise as may be desired. The protractor gauge 149 has a swinging blade 151 hinged thereto at 152, and a curved arm 153 extends rearwardly Vfrom the blade 151 across the stationary blade 148, there being a clamping means provided at 154 for the purpose of locking the blades 148 and 151 in any desired relative position. It may be advisable to mark the curved member 153 in degrees so that the angle of the gauge member 149 may be quickly set. In Fig. 8 I show the tool head 41 rotated into position with its working face 75 at right angles to the length of the table, so that the saw 140, held in the spindle 71 thereotl will be in proper position for crosscutting or mitering. A board 154 placed against the gauge member 151 in the manner shown will be cut off by the saw 140 at any desired angle to which the gauge is set.

In Fig. 10 I show' the angle head 84 turned diagonally to the Work 155, thereby placing the saw 140 in an inclined position so that a bevel edge 156 will be cut on the work when the tool head is moved to advance the saw in proper direction. Attention is called to the simplicity and ease With which the woodworking machine is set up to perform the many operations required in fine cabinet making, door litting, etc. The cumulative eliect of an entire woodworking shop of the present type is attained in the use of a single machine embodying the invention, and the operations may be performed consecutively on the work which is mounted horizontally on the table 15, by setting up the tool head or angle head with proper tools, and in nearly every instance without the necessity of repeatedly moving the work from position to position for the reason that the important feature of the woodworking machine is to move the tool in any direction relative to the work, instead of moving the work relative to the tool as is necessary in a greater portion of the wood- Workin@ equipment now in use.,

For cross-cut work such as illustrated in Fig. 8, or tor any other operation in which the cross-carriage is employed, it may be desired to manually move the tool head 41, therefore, for the purpose of releasing the lead screw 133 so that the cross-carriage 31 may move freely in its guide or tracks, I desire to employ a split nut which may be as shown in Fig. 9 in which upper and lower half nut-s 170 and 171 are shown vertically slidable upon a vertical plate 172, there being a member 173 extending upwardly from the lower ialt 171, this member 173 having a pivot 174 supporting a cam 175 which may be rotated by a pull rod 176 which engages the extending lever 177, the cam 175 thereon forcing down on the half-nut 170 and drawing up on the halt-nut 171, with the result ot closing the nut on the screw 133. It is desirable to clamp one or the other or both of the carriages 22 and 31, as occasion may require, and for this purpose any of the various known locking or clamping devices may be used, a simple form thereof being shown at 180 in Figs. 1 and 2, applied as a lock for the traveller 22, it being understood that a similar lock may be employed for the cross-carriage.

In the enlarged crossesection, Fig. 12, I show the casing 180 with a vertical slide-bar 181 supporting clamp blocks 182 and 183 which are forced together by a screw 184 so as to clamp the outstanding portions 2O of the track members 19. A suitablelock for the tool head 41 has the form of a. block 185 adapted to be clamped against the rack 49 by a screw 186 having its head exposed for en-v gagement of a wrench. Although I have illustrated and described my invention in operation with a limited number ot the different types of tools, the expert will readily understand and appreciate that nearly every type of tool may be employed in either ot the spindles of the Inachine, so as to perform a practically unlimited variety of operations-` By the use of a milling cutter on an arbor placed in the spindle a more accurate job of jointing may be done than possible in the'present type of equipment where the work or lumber is moved by hand across the cutter, for the reason that the jointing tool is moved through a definite true plane when the selected carriage is moved along its tracks, thereupon trimming the edge ofthe material to a true plane. Sanding, either by drum or disc, is done with greater facility than now obtained in present sanding equipment, and the machine may be quickly set to cut complex combination skew or bevel miters such as employed in rafter work.

From the foregoing the great variety of uses of the equipment may be readily perceived and for the purpose of simplicity in exposition I have shown my invention in its most simple form. VIt is advisable to here point out that I intend to employ all equivalents known to the mechanical arts and that the invention is not limited by the simplicity of the foregoing disclosure, but is to be limited solely by the hereafter stated claims.
